I have zero ideas on PVP. Everything I'm about to say is applicable to PVE only.
I also have very little direct experience with Poison. I have a level 18 or so Illusion/Poison character so I don't have a lot to work with there.
I'm much more familiar with Ice Control, having played it to 50 twice on Controllers and once on a Dominator (who is now essentially my "main" incarnate raider).
Without being able to see a build it's impossible to suggest anything specific. However, in general I would be leaning toward the following:
Alpha -- Cardiac. This helps enormously in curbing endurance costs, extends range, and provides some extra damage resistance if you have Tough and a resistance armor.
Judgment -- Hard to say but probably Ionic. The Darkness one is also really great if you don't mind the PBAoE aspect. Just probably not a cone.
Interface -- Probably Cognitive for the extra confusion blanket.
Destiny -- I've tried 3 on my Ice/Fire Dominator. Of those, Barrier turned out to the best on him by far. This is based on two assumptions: 1) your endurance is under control enough that you can skip Ageless, and 2) you have mezz protection from the Psi pool (IMO usually a better source of mezz protection than Clarion, because then you can devote your Destiny to something else). Poison has no significant endurance recovery powers and from what I can see is endurance heavy, so YMMV here.
FWIW at one time my Ice/Fire Dom was set up differently: Spiritual Alpha, Ageless Interface. Swapping it around to Cardiac/Barrier greatly improved his capabilities. I'm not sure whether all Ice characters could get away with it, because being perma dom he gets an endo refill every 90 seconds, plus has Consume for more recovery. But on that particular character I can now easily fight lvl 54 Rikti with very little fear. A Controller probably wouldn't have the damage for that, but it should be able to do it in about as much, if not more, safety.
just need some new and awsome suggestions for my ice/poison build like:
judgement?
Interface?
Alpha?
as well as some suggestions for epics and a alternate build as well
This will be used for pvp
